A good thing happened when engineering came into existence to help solve most natural, societal and individual problems. Since crude oil was discovered, its usefulness has given a tremendous and phenomenal impact and contributions to the existence of mankind and his comfort. Over the years crude oil has been the most used natural resources because its requirement brought about the refined products such as petrol, kerosene, diesel, and gas has made man’s engineering inventions to be affiliated to the sue of crude oil. Inventions like generators, vehicles, stove, etc cannot function without the use of these petroleum products. Generators are now part of our lives. In Nigeria and some other part of West Africa, no thanks to epileptic power supply. This has made refueling generators a common part of the daily lives of ordinary Nigerians and this is normally done by sucking with the mouth i.e. one has to fix one end of a hose into a fuel container and his mouth as an extracting machine which then allows the flow of fuel from the container to the tank.
